+### Configuring code actions on save
+
+The `code-actions-on-save` key lists LSP code actions to run (in order) when
+the buffer is saved. The available actions depend on available language servers,
+below are common examples and may need adjusting for your setup.
+
+```toml
+# Python with ruff
+[[language]]
+name = "python"
+code-actions-on-save = ["source.organizeImports", "source.fixAll"]
+
+# TS/JS with tsserver
+[[language]]
+name = "typescript"
+code-actions-on-save = ["source.addMissingImports.ts"]
+
+# TS/JS with eslint
+[[language]]
+name = "javascript"
+code-actions-on-save = ["source.fixAll.eslint", "source.organizeImports"]
+```
+
 ## Language Server configuration
 
 Language servers are configured separately in the table `language-server` in the same file as the languages `languages.toml`
